Teeb meem 2: Plasticity tsawg
Lwm qhov teeb meem uas tuaj yeem tshwm sim nrog HPMC hauv cov hmoov putty yog tias nws tuaj yeem txo cov plasticity ntawm qhov sib tov.Qhov no txhais tau hais tias cov hmoov putty yuav tsis kis tau yooj yim raws li nws yuav tsum tau, thiab nws yuav nyuaj dua kom ua tiav ib tug du, txawm nto.
Kev daws: Siv ntau hom HPMC
Ib txoj hauv kev los daws qhov teeb meem no yog siv ntau hom HPMC uas tau tsim tshwj xeeb los ua cov yas ntau dua.Muaj ntau ntau hom HPMC, qee qhov tshwj xeeb tsim los siv nrog cov hmoov putty.Los ntawm kev siv ib qho ntawm cov khoom no, koj tuaj yeem xyuas kom meej tias cov hmoov putty muaj cov yas zoo, ua kom yooj yim rau kev thov thiab ua tiav cov nyhuv xav tau.
Teeb meem 3: ncua kev kho
Qhov thib peb qhov teeb meem nrog HPMC nyob rau hauv putty hmoov yog tias nws ncua lub sij hawm kho ntawm qhov sib tov.Qhov no txhais tau tias cov hmoov putty yuav siv sij hawm ntev dua kom qhuav thiab teeb, uas tuaj yeem ntxhov siab rau cov neeg siv uas yuav tsum tau ua haujlwm sai.
Kev daws: Kho HPMC ntau npaum li cas
Txhawm rau daws qhov teeb meem no, tus nqi ntawm HPMC hauv qhov sib tov tuaj yeem hloov kho.Los ntawm kev ua tib zoo tswj hwm tus nqi ntawm HPMC, lub sijhawm kho ntawm cov hmoov putty tuaj yeem ua kom zoo, kom ntseeg tau tias nws qhuav sai sai yam tsis muaj kev ncua.Qhov no yuav xav tau qee qhov kev sim nrog qhov sib txawv, tab sis los ntawm kev nrhiav qhov sib npaug, qhov teeb meem no tuaj yeem daws tau zoo.
HPMC yog cov khoom muaj txiaj ntsig zoo uas txhim kho kev ua haujlwm ntawm cov hmoov putty.Txawm li cas los xij, muaj qee qhov teeb meem uas yuav tsum tau paub txog, tshwj xeeb yog hais txog adhesion, plasticity thiab kho lub sijhawm.Los ntawm kev nkag siab txog cov teeb meem no thiab siv cov kev daws teeb meem zoo, nws muaj peev xwm tsim cov hmoov putty zoo uas ua tau raws li cov neeg siv khoom xav tau.Los ntawm kev ua kom muaj txiaj ntsig zoo rau cov kev cov nyom no, peb tuaj yeem ua kom ntseeg tau tias HPMC tseem yog ib qho tseem ceeb rau kev tsim kho kev lag luam.
